Natural gas from has been transported to Gas Germany through the 1,224 km-long Baltic Sea turbine OPAL NEL pipeline since 2011. The gas is fed into the German gas grid in Lubmin. Cold gas Heat Electric power Warm gas Exhaust It arrives there at a pressure of more than 100 bar. To be able to transport it further through the gas grid at a maximum pressure of 100 bar, it must be Combined heat and warmed before the pressure is reduced. power – flexible and This task is performed in Lubmin by a natural- decentralised. gas-fired gas turbine plant using highly efficient combined heat and power (CHP). Combined heat and power (CHP) technology uses fuel to generate electrical energy and useful heat at the same time. The best results are attained when natural gas is used, as it is the most environmental- ly friendly fossil fuel. Because the plant uses both electricity and heat at the same time, the energy efficiency rate is much higher than with convention- al power plants that only generate electricity. This reduces the fuel requirements for supplying heat and electricity, and hence the plant‘s harmful emis- sions. In addition, it generates electricity and heat locally where they are needed (decentrally), which reduces the load on the energy supply networks. Combined heat The heat from the exhaust gas is harnessed using a modern, highly efficient exhaust-gas heat ex- and power at the changer from Viessmann OMNICAL.

The gas turbine can thus respond in seconds to the needs of the electricity market, irrespective of the heat requirements of the land- ing terminal. The CHP plant thus helps balance fluctuations in regenerative power generation in the grid quickly and flexibly. As a result, natural gas makes an important contribution to ensuring supply security in the electricity sector, making it an indispensable partner in the energy transition.

The heart of the plant is the SGT 750 gas turbine from Siemens. The turbine was deployed here for the first time worldwide and is more efficient, more flexible, easier to maintain and, above all, more environmentally friendly than conventional plants. Riga
